4. Electrical Specifications

4.1 Recommended operating conditions

Table 4-1 Recommended operating conditions

Parameter Min Type Max Units

Storage temperature -30 +25 +85 °C

Recommend operating temperature

(3GPP compliant) (*1)

-30 +25 +70 °C

Extendable (with limited performance)

Temperature measure on T77W968 module(*2)

-40 +85

Operating voltage 3.135 3.3 4.4 Vdc

Note: The operating temperature reference point is board temperature on module bottom side (Ground Golding

plating area)

(1)Refer application note about thermal mitigation plan

(2).Extendable operation allows normal mode data transmission for limited time until

automatic thermal shutdown takes effect. Within the extendable temperature range (outside

the operating temperature range) the specified electrical characteristics may be degraded.

(3).Due to temperature measurement uncertainly, a tolerance on the stated shutdown

thresholds may occur. The possible deviation is in the range of +/- 2 ℃ at the

over-temperature and under-temperature limit.

(4). Need implement thermal solution on Platform (Example add thermal pad to heat

dissipated from LTE module to Platform PCB) would get more thermal margin and benefit

then extend the operating temperature

Operating T77W968 device under conditions beyond its absolute maximum ratings (Table

4-1) may damage the device. Absolute maximum ratings are limiting values to be considered

individually when all other parameters are within their specified operating ranges. Functional

operation and specification compliance under any absolute maximum condition, or after

exposure to any of these conditions, is not guaranteed or implied. Exposure may affect

device reliability
